The Italian government recently decided to move forward with planning for the construction of underwater, mobile floodgates to mitigate flooding in Venice, situated on islands in a lagoon in the Adriatic Sea. The soundness of the plan is discussed by several scientists in the May 14 issue of Eos, published by the American Geophysical Union.
The approved plan to protect Venice, called MOSE (Modulo Sperimentale Elettromeccanico, or Experimental Electromechanical Module), involves the construction of 79 gates at three lagoon inlets. When waters rise 1.1 meters [43 inches] above "normal," air will be injected into the hollow gates, causing them to rise, blocking seawater from entering the lagoon and thereby preventing the flooding of Venice. The floodgates will take approximately eight years and $2.6 billion to construct.
Some critics of MOSE, such as Paolo Antonio Pirazzoli of the French Centre National de la Recherche Scientifique (CNRS), are skeptical as to whether the gates will actually prevent flooding. In his Eos article, Pirazzoli states that the design of the gates is based on outdated predictions of sea-level change, utilizing a scenario that differs by nearly 0.26 meters [10 inches] from recent estimates of rise in sea level over the next century, made by the Intergovernmental Panel on Climate Change (IPCC). Pirazzoli also
asserts that the MOSE designers did not consider sea-level rise associated with land subsidence or increased water levels associated with extended rainy or windy periods.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
